Prevagen Remains Popular Despite No Supportive Evidence

Prevagen was listed as the number one pharmacist recommended memory support supplement in the 2020 Pharmacy Times survey. But Quincy Bioscience, the Prevagen manufacturer, recently settled a nationwide class action lawsuit for making deceptive claims. Make sure you understand the facts about this popular product.

Prevagen contains apoaequorin. It’s a calcium-binding protein that comes from the jellyfish species Aequorea victoria. Because apoaequorin has a similar structure to human calcium-binding proteins, some theorize that it might help regulate calcium in the brain and reduce memory loss. But one manufacturer-sponsored study shows that taking apoaequorin daily only slightly improves memory in older adults – there isn’t any high-quality research confirming this.

Under the settlement agreement, Quincy Bioscience must update product labeling, removing deceptive claims and adding appropriate disclaimers. They also must provide partial refunds to about 3 million consumers. If patients ask you about Prevagen, tell them there’s no convincing evidence that it works – and it’s likely not worth the $40 for a monthly supply. Instead, recommend regular exercise, proper sleep, and a balanced diet to support cognitive health.
